ROBERT REED, OF ROCKWALL, TEXAS.

CRUDE-OIL BURNER.

Application 1ed January 24, 1911.

To @ZZ whom it may concern.'

Be it known that I, ROBERT REED, a citizen of the United States,residing at Rockwall, in the county of Rockwall and State of Texas, haveinvented a new and useful CrudeOil Burner, of which the following is aspecification.

This invention relates to crude oil burners for use in ranges, furnacesand the like, the burner being of that type adapted to be placed uponthe grate bars ordinarily employed and whereby crude oil may be used inlieu of coal or similar fuel.

The object of this invention is to provide a compact burner cheap tomanufacture and which will not readily get out of order, means beingprovided whereby an abundant supply of air may be mixed with the fuel toinsure practically perfect combustion.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invent-ion resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings, the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a central vertical longitudinal sectionthrough the burner, a portion of the tank being shown in connectiontherewith. Fig. 2 is a view partly in plan and partly in section of theburner. Fig. 3 is a section on line A-B Fig. 1, the nozzle being shownin elevation. Fig. 4 is a perspective view of one end of a nozzle fordirecting fuel into the mixing chamber.

Referring to the figures by characters of reference 1 designates apan-like base having a central opening 2, and fastening bolts 3 areextended through the pan adjacent this opening at diametrically opposedpoints. These bolts are adapted to detachably engage slotted ears 4extending in opposite directions from a downwardly projecting tubularextension 5 formed at the center of a cylindrical member 6 closed at itsends and forming the mixing chamber of the burner. This member 6 ispreferably formed of two oppositely arranged similar castings heldtogether by means of a tie bolt 7 or the Specification of LettersPatent.

like and tubular extensions 8 project downwardly from the end portionsof this mixing chamber and terminate above the top of the base 1, theseextensions forming fuel outlets. Vent openings 10 are formed in the topof the mixing chamber adjacent the ends thereof and preferably directlyover the outlets 9.

A fuel conducting pipe 11 is supported axially within the mixing chamberand has a laterally and backwardly extending portion 12 lying parallelwith and close to one side of the mixing chamber, there being nozzles 13extending laterally from said portion 12, and through 'openings formedin one side of the mixing chamber. Each nozzle is preferably made of ashort length of pipe having longitudinal slits 14 extending into thefree end thereof and plugs 15 of metal `or other suitablenon-combustible material are forced into the ends of these pipes so thatfuel can only escape through the unclosed portions of the slits 14. Afuel tank 16 is supported above the burner at any desired distancetherefrom and is connected by a pipe 17, to a valve casing 18 arrangedat one end of the pipe 11, said casing having a needle valve 19 arrangedtherein so that the supply of fuel may be readily controlled.

By referring to the drawings it will be noted that the nozzles 13 arelocated above and at one side of the fuel outlets 9. It will be seentherefore, that when the valve 19 is opened, fuel will be dischargedinto the pipe 11 and sprayed therefrom through the slots 14 in thenozzles. `When the fuel is ignited upon the pan or base 1 it willthoroughly heat and vaporize that portion of the fue1 contained withinthe pipe 11 and the vapor thus produced will mix with air drawn into thechamber through the opening 5. A highly combustible mixture will thus beproduced and the iiames discharged through the openings in theextensions 8 will strike the base 1 and be spread laterally thereon thusenveloping the mixing chamber 6 and insuring the rapid vaporization ofthe fuel and its thorough commingling with the air supplied to thechamber. It will be noted that the burner is formed of but three parts,to wit the base 1, and the two sections constituting the mixing chamber.The pipe 11 can be readily placed in position within the mixing chambermerely by detaching the two parts forming said chamber.

A device such as has been described can be easily placed 0n the grate ina fire box and it has been found, in practice, that practically allparts of the fuel are completely consumed. It will be noted, also, thatthere are no small orifices likely to become choked. When it is desiredto clean the burner the various parts can be readily disconnectedwithout requiring the services of a skilled mechanic.

What is claimed is A crude oil burner including a pan hav ing an openingin the center of the bottom thereof, a mixing chamber consisting` ofconnected sections having coperating means forming an air inletregistering'with the opening in the pan and constituting means forsupporting the mixing chamber above the pan, tubular outlet extensionsupon the mixing chamber and directed toward the pan,

said extensions constituting means for directing fuel downwardly intothe pan, there being vent openings in the mixing chamber and above thefuel outlets, a. fuel conducting pipe extending longitudinally throughthe 25- mixing chamber and supported by the end walls thereof, said pipebeing extended along one side of the chamber and above the pan, andnozzles extending from the pipe and into the mixing chamber at one side30 ROBERT REED.
